Intervention Type: Device
Study Type: Interventional
Study Phase: Not Applicable
SUMMARY
The purpose of this study is to compare two treatments for acne scars on the face. The study will test whether fractional lasers (Erbium:Glass and Thulium) lead to better improvement in acne scars than microneedling.
